New Britain–New Ireland Montane Rain Forests
The New Britain–New Ireland montane rain forests is a tropical and subtropical moist broadleaf forests, tropical moist forest ecoregion in Papua New Guinea. The ecoregion includes the mountain rain forests on the islands of New Britain and New Ireland (island), New Ireland, which lie northeast of New Guinea. Geography The ecoregion includes the montane rain forests on New Britain and New Ireland, two large islands in the Bismarck Archipelago lying northeast of New Guinea. It includes the portions of both islands above elevation.Wikramanayake, Eric; Eric Dinerstein; Colby J. Loucks; et al. (2002). ''Terrestrial Ecoregions of the Indo-Pacific: a Conservation Assessment.'' Washington, DC: Island Press. New Britain is the largest island in the ecoregion, with an area of . New Ireland is the second-largest, with an area of . The archipelago is mostly made of volcanic rocks, with extensive areas of limestone. Several of the ecoregion's volcanoes are still active.

Mount Ulawun
Ulawun is a basaltic and andesitic stratovolcano in West New Britain, West New Britain Province, on the island of New Britain in Papua New Guinea. About southwest of the township of Rabaul, Ulawun is the highest mountain in New Britain and the second in the Bismarck Archipelago at , and one of the most active volcanoes in Papua New Guinea. A total of 22 recorded eruptions have occurred since the 18th century; the first, in 1700, was recorded by William Dampier. Several thousand people live near the volcano. Because of its eruptive history and proximity to populated areas, Ulawun is considered one of the Decade Volcanoes. Recent activity The last few years have seen almost constant activity at Ulawun, with frequent small explosions, and have caused great damage and loss of life. The volcano erupted at approximately 7am on 26 June 2019, and was quickly upgraded to a major Plinian eruption, sub-Plinian eruption, with ash climbing to . Over 5000 people were evacuated, and flights ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanopsis Acuminatissima
''Castanopsis acuminatissima'' is an evergreen tree native to Southeast Asia and New Guinea. It is known by a variety of common names over its range, including white oak, New Guinea oak, Papua New Guinea oak, ''ki riung, ko-duai, ko-soi, ko-mat, meranak'', and ''riung anak.'' Description ''Castanopsis acuminatissima'' is a large canopy tree, up to 40 meters in height. The trunk is markedly fluted, and sometimes buttressed.

Australasian Ecoregions
Australasia is a subregion of Oceania, comprising Australia, New Zealand (overlapping with Polynesia), and sometimes including New Guinea and surrounding islands (overlapping with Melanesia). The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific ( Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian coloni ...

Bismarck Honeyeater
Gilliard's honeyeater (''Vosea whitemanensis'') or the Bismarck honeyeater, is a bird species in the family Meliphagidae. It is the only species placed in the genus ''Vosea''. It is endemic to New Britain. Its natural habitat is subtropical or tropical moist montane forests. Gilliard's honeyeater was described by the American ornithologist Thomas Gilliard in 1960 from specimens collected in the Whiteman Mountains on the island of New Britain in the Bismarck Archipelago. Gilliard introduced the genus ''Vosea'' and coined the binomial name ''Vosea whitemanensis''. The genus name ''Vosea'' was chosen to honour the memory of Charles R. Vose (1890–1957), a US businessman, explorer and sponsor. The specific epithet ''whitemanensis'' is from the type locality. The species was formerly placed in the genus ''Melidectes'' but was transferred to its own genus ''Vosea'' based on the results of a molecular phylogenetic study published in 2019. The species is monotypic: no subspecies are re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bismarck Thicketbird
The New Britain thicketbird or Bismarck thicketbird (''Cincloramphus grosvenori'') is a bird species. It used to be placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. It is found only in the rarely visited highlands of the island of New Britain in Papua New Guinea. This little-known species was for long classified as a data deficient species by the IUCN, due to the general lack of reliable data on its distribution and numbers. While there have been no records since its discovery in 1959, recent evidence suggests the habitat destruction in the Bismarck Archipelago presents a greater risk than previously believed, leading to the Bismarck thicketbird being listed as a Vulnerable species in the 2008 red list.BLI (2008) It used to be considered conspecific with the Santo thicketbird and the Bougainville thicketbird.

New Britain Goshawk
The New Britain goshawk (''Tachyspiza princeps'') is a bird of prey species in the family Accipitridae. It is endemic to Papua New Guinea. This species was formerly placed in the genus ''Accipiter''. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. Formerly classified as Near Threatened by the IUCN, it was suspected to be rarer than previously assumed. Following the evaluation of its population status, this was found to be correct, and it is consequently uplisted to vulnerable status in 2008. The first-ever photograph of a New Britain goshawk was taken in March 2024 in the Pomio District of New Britain New Britain () is the largest island in the Bismarck Archipelago, part of the Islands Region of Papua New Guinea.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Marsupial
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muridae
The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia. The name Muridae comes from the Latin ' (genitive '), meaning "mouse", since all true mice belong to the family, with the more typical mice belonging to the genus ''Mus (genus), Mus''. Distribution and habitat Murids are found nearly everywhere in the world, though many subfamilies have narrower ranges. Murids are not found in Antarctica or many oceanic islands. Although none of them are native to the Americas, a few species, notably the house mouse and black rat, have been introduced worldwide. Murids occupy a broad range of ecosystems from tropical forests to tundras. Fossorial, arboreal, and semiaquatic murid species occur, though most are terrestrial animals. The extensive list of niches filled by murids helps to explain their relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros Salomonensis
''Metrosideros'' is a genus of approximately 60 trees, shrubs, and vines in the family Myrtaceae, mostly found in the Pacific region. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek ''metra'' or "heartwood" and ''sideron'' or "iron". Perhaps the best-known species are the pōhutukawa (''M. excelsa''), northern rātā (''M. robusta'') and southern rātā (''M. umbellata'') of New Zealand, and '' ōhia lehua'' (''M. polymorpha'') from the Hawaiian Islands. Distribution ''Metrosideros'' is one of the most widely spread flowering plant genera in the Pacific. New Caledonia has 21 species, New Zealand has 12, New Guinea has seven and Hawaii has 5. The genus is present on most other high Pacific Islands, including Solomon Islands, Vanuatu, Fiji, Samoa, Cook Islands, French Polynesia, Bonin Islands and Lord Howe Island, but absent from Micronesia. The genus is also represented by one spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
